That distinction — a hard inequality on what is thermodynamically permitted, as opposed to a causal story about why anything organizes itself to approach that permission — is the difference between England’s 2013 result, which is uncontroversial physics, and the more ambitious theory built on top of it two years later, which is not. The 2013 bound is compatible with, and in fact numerically consistent with, Bennett’s independent estimate that real biological replication machinery dissipates on the order of tens of T per step [ 4 ] — both results describe the same underlying fact, that copying is not free, from two different derivations three decades apart. Neither result, on its…
